DOOR/CHECK.

Application filed August 11, '1928. Serial No. 299,044.

The present invention relates to improvements in door checks and has tor its prin- 'cipal object to provide a device for attachment on a door frame to retard the door, during the movement of the same to a closed position, so as to prevent slamming'thereof.

One of the important objects of the present invention is to provide a door check of the above mentioned character, which is adapted to be variably tensioned, so as to regulate and control the outward or lateral projection, ot the striking member against which the door engages during the swinging movement of the door to a closed position.

Still afiturther object is to provide a door check of the above mentioned character which will, at all times be efficient and reliable in its operation, the same being further simple in construction, inexpensive, strong and durable.

Other objects and at *antages of the invention will become apparent as the nature of the invention proceeds and when taken in connection with the accompanying drawings;

In the accompanyingdrawiugs, forming a part oi this application and wherein like reference characters designate like parts throughout the several views:

Figure '1 is a't'ront elevation of a door and the frame therefor showing my improved door check attached to the top of the frame.

Figure 2 is a similar view showing the door check attached to the side of the frame.

Figure 3 is a rear elevation of the door check for more clearly disclosing the rectangular shaped base plate.

Figure 4 is a side ele *ationotthe door check.

.l igure 5 is a top plan view thereof.

Figure 6 is a top plan view, showing the manner in which the door check cooperates with the upper end of avertically swinging door, during the closing movement of said. door. I

Figure 7 is a view, similar to Figure 6, showing a modified form of the door check for association with the free edge of the door, and

Figure 8 is a further modification as attached to the top of the frame for cooperation with the upper edge of the door.

In the drawings, wherein for the purpose of illustration is shown the preferred embodiment of my invention, with reference more particularly to Figures 3, at, and 5, the

numeral 1 designates a substantially rectangular shaped base plate that is formed at its respective corners with openings 2 for receiving attaching screws or the like, for rigidly securing the base plate on the door frame either at the top or side thereof as shown in Figures 1 and 2. A horizontally disposed arm 3 extends outwardly from the front side of the intermediate portion of the base plate 1 and is integrally associated with the base plate. A brace bar 4 is provided for thelaterally extending arm 3 and as is clearly shown in Figure 4, the inner end of the brace bar is connected to the upper edge portion of the base plate 1, while the outer end portion of this bar extends inwardly and is connected to the outer end portion of thearm 3.

The invention further comprehends the provision of the door obstructing member in the form of the elongated flat bar 5 that is disposed below the lower edge of the base plate 1 and the laterally extending arm 3 in parallel spaced relation thereto. The

outer-end ot the bar is curved upwardly and inwardly to provide the rounded nose 6, the free end of said nose terminating at the outer end of the arm 3, as clearly shown in Figure at.

A pair of beaded rods 7 and 8 respectively are secured on the upper face of the bar 5, at the intermediate portion thereof and these rods extend upwardly and the upper ends of the rods are threaded for disposition through openings provided therefor in thelaterally extending arm The head on the lower end of each rod is shown at 9, and these heads may be secured to the bar 5, in any suitable manner.

The rods 7 are slidablydisposed through the sleeves 10 and are fixedly secured. at their upper ends to the under sides of the arms 3, said sleeves beingot a length less than the length of the rod and it is of course to be understood that the diameter of the sleeve is materially greater than the respective rod, so as to permit the lateral movement of the rod with respect to the sleeve, during the operation of the obstructing member in checking the closing movement of a. swinging door.

An expansible coil spring 11 encircles each of the sleeves 10 and is disposed between the arm 3 and the head 9 of the respective rod for normally urging the obstructing member downwardly. A nut 12 is threaded on the upper end of each rod for regulating the tension of the respective coil springs.

In Figure l, the door check is illustrated as being secured on the door frame A, at the top portion thereof, so that the obstruct ing member of the door check will cooperate with the upper edge of the vertically swinging door 15 suggestedin Figure 6. The spring urged bar 5 will be within the path of the upper edge of the vertically swinging door, so that during the closing movement of the door, the bar 5 will. be engaged by the upper edge of the door, so as to check the closing of the door and prevent its slamming.

In Figure 8 there is shown a modification of the door check, wherein the arm and the brace thereof as well as the obstructing member for cooperation with the upper edge of the door is slightly curved. Otherwise, the construction of the door check shown in Figure 8 and denoted generally by the reference character 13 is identical with the door check shown in Figure In Figure 2, there is illustrated the attachment of the door check to the side of the door frame A, adjacent the free edge of the vertically swinging door B, so that the obstructing member of the check will engage with the vertical free edge of the swinging door, to prevent the slamming thereof during the closing movement of the door.

As more clearly shown in Figure 7, the obstructing member is slightly rounded, so that the concaved face of the obstructing member will properly engage with the vertical fr e edge the swinging door. This particular modification of the door check that is to be mounted on the side of the door frame denoted generally by the reference character 14. l

The outward projection of the bar 5, which arrests the motion of the door as it is swung shut can be regulated by tightening or loosening the rod for adjusting the tension of the coil springs.

It will thus be seen from the foregoing description that I have provided a door check that can be readily and easily attached on a door frame for arresting the shutting .of the door so that slamming thereof will be prevented, yet permitting the door to be properly closed and opened, without the exercise of much effort. The siniplicity of my improved door check enables the same to be constructed at a very low cost, and the same will be strong and durable and at all times positive and etlicicnt in carrying out the purposes for which it is designed.

.Vhile l have shown the preferred (:llllJOC iment of my inveiition, it to be understood that various changes in the size, shape and arrangement of parts may be resorted to, without departing from the spirit of the invention or the scope of the appended claims.

I claim:

1. A door check comprising a base plat an arm entending laterally therefrom, a door door eng ging bar independently of said arm a d disposed in spaced relation with res ect the o, bolts secured to the inner face of the bar, the threaded ends of the bolts extending through openings formed in the arms, a nut threaded on the end of the bolt for engagement with said arm, and resilient means disposed between the arm and the bar for normally urging the bar outwardly with respect to the arm, said bar being movable inwardly toward the arnn ag nst the action of the resilient means when the bar is engaged the door during the setting thereof.

2. A door check comprising a base plate, an arm extending laterally therefrom, a door engaging bar arranged in spaced relation with respect to the arm and being indeoendout with respect to the arm, bolts attached to the bar and extending through openings provided in said arms, nuts threaded on the threaded ends of the bolts for ei'igagement with the outermost face of the arm, and coil springs for encircling the bolts for disposition between the arm and said bar, for normally urging the bar outwardly with respect to the arm so as to be engaged by the door during the swinging movement of the latter to a closed position, said bar moving inwardly toward the arm against the tension of the coil. spring during the closing of the door.

In testimony whereof I ailix my s OTTO E. lVElTZ.
